Answer:
Step-by-step explanation:
In the picture the 2 adjacent sides appear to be congruent.
So let's label one - x, so the other one is also x.
And using Pythagoras' Theorem.
Answer:
4x+4=-3x-10
4x+3x=-10-4
x= -14

Answer:
x=30
Yes, they are complementary
Step-by-step explanation:
The two angles shown add up to the right angle marked. Right angles are 90 degrees. Set up the following equation:
2x°+x°=90
3x°=90
x=30
Complementary angles are two angles that add up to 90°. Since the two angles add up to 90 degrees, they are complementary.
